Single crystals and two‐dimensional crystalline assemblies of block copolymers

چکیده
Block copolymer single crystals (BCPSCs) have attracted widespread attentions due to their unique two-dimensional (2D) structure, good controllability, and great potential applications in recent years. In this paper, the morphology, surface structure of BCPSCs related influencing factors are reviewed. We also summarize studies 2D crystalline assemblies block copolymers (BCPs) driven by crystallization intermolecular π–π interaction. Moreover, functionalization properties BCPs introduced. Finally, we put forward some unsolved problems field.

Rapid self-assembly of brush block copolymers to photonic crystals.
The reduced chain entanglement of brush polymers over their linear analogs drastically lowers the energetic barriers to reorganization. In this report, we demonstrate the rapid self-assembly of brush block copolymers to nanostructures with photonic bandgaps spanning the entire visible spectrum, from ultraviolet (UV) to near infrared (NIR). Linear relationships were observed between the peak wav...
متن کاملPerforated layer structures in liquid crystalline rod-coil block copolymers.
We report a novel observation of the tetragonal perforated layer structures in a series of rod-coil liquid crystalline block copolymers (BCPs), poly(styrene-block-(2,5-bis[4-methoxyphenyl]oxycarbonyl)styrene) (PS-b-PMPCS). PMPCS forms rigid rods while PS forms the coil block. Differential scanning calorimetry (DSC), polarized light microscopy (PLM), small-angle X-ray scattering (SAXS), wide-ang...
متن کاملHybrid assemblies of Eu-containing polyoxometalates and hydrophilic block copolymers with enhanced emission in aqueous solution.
Polyoxometalates (POMs), a type of giant transition metal oxide clusters on the nanoscale, are emerging as useful materials with unique catalytic, electrooptical, and biological properties. Lanthanide-containing POMs elements show excellent photoluminescent properties with narrow emission bands, large Stokes shift, long lifetime, and tunable emission, i.e., their long emission timescale (microt...
